    Ok so whenever I make a project that normall works fine on iPhone simlulator 4.0 it installs on simulator fine. But if I try to run the iPhone 3.13 simulator the app simply crashes on startup, with no warnings or errors. Even when I click file > new project > build and run It still crashes in iPhone simulator 3.13 and works fine in 4.0 Help please :(

    The Ivory Tower (I'm not coming down)
    I don't know much about the simulators, but the problem is probably due (at least in part) to you trying to run software built on the 4.0 framework on an older version (3.1.3).

    Hmm that makes sense, but when without even writing a bit
    of code it still only installs on 4.0 simulator how do I fix this : /

    This crash is not "for no reason", it makes perfect sense..

    You need to run a 4.0 App in the 4.0 simulator. Simple. If you want it to also run on a lower simulator or device which i assume is what your asking, you need to set the minimum build target to whatever you need (3.1.3, 3.0 so on). This should fix it!

    If not, then its a bug and you need to submit a bug report to Apple.
